Be it known that 1, CHARLES a citizen'of the United States, and aresident of Bar Harbor, in the county of Hancock and State of Maine,have invented a new and Improved Selective Controlling Mechanis Of whichthe following is a full", clear, and exact description. w

The invention relates to selective controlling devices for automobilesand other m'otor vehicles and machines, andthe object'of the inventionis to provide a new and improved selective controlling mechanismarranged to enable the operator in charge of the machine to readilyactuate the gear shifting mechanism or the brake mechanisms or otherdevices through the agency of a single pedal, thus leaving thepperatorshands free for other work. Another object is to hold the selectivecontrolling mechanism in the selected position on the operator removingthe foot from the pedal. Another object is to permit of applying theselective controlling mechanism to devices to be actuated withoutrequiring altering of the construction of such devices.

With these and other objects in view, the.

invention consists of certain novel features of construction ashereinafter shown and described and then specifically pointed out in'the claims.

. A practical embodiment of the invention is represented in theaccompanying draw- Fig. 3 is an enlarged plan view of the pedal withparts shown insection; Fig.4 is a cross section of theselectivecontrolling mechanism on the 'line' l4 of" Fig. 5 is a side elevation ofthe selective controlling mechanism arranged for actuating the gear setof a Ford automobile, parts being shown in section;

Fig. 6 is a sectional plan V16W'0'f the same Fig. 7 is a plan view ofthe selective controlllng mechanism arranged for actuating the serviceand emergency brakesof an auto-' mobile and F. Mans'ron,

' Fig. 8 is a sectional side elevationof a trolling mechanism shown inFigs. 1, 2 and 3 is mounted to swing up and down and to slide sidewiseon a pivot 11 held on the outer ends of cylindrical casings 12 (seeFig.3) attached toarms 13 on a head 14 secured on the upper end of astem'or a post 15. On thepivot 11 are coiled two springs 16ers tendinginto the casings 12 and pressing opposite sides of the pedal 10 tonormally hold the latter in a central position, that is, approximatelymidway between the casings 12, but to allow of shifting the pedalsidewise either to the right or to the left or to .swingthe pedal up ordown. In order to facilitate the sidewise movement of the pedal 10, thelatter is providednear its for.- ward end with side flanges 17 and 18adapted to be engaged by the "sides of the foot of pedal 10 is alsoprovided at its rear end with a heel rest 1.9 to permit of convenientlyrocking the pedal in an up and down direction.

On the head 1 1 is arranged a set screw 20 to limit thedownward rockingmovement of the pedal 10. The stem 15 extends throughan opening 25arranged in the floor 26 of theautomobile and the lower end of the stem15 is adjustably secured in the split end 27 of a swing- 1 g-support 28by'the use of a clamping screw 29, as plainly indicated in Figs. 1 and2. The support 28 is provided with two side members 29 and 30 mounted toswing' at their free, ends on a. transverse rod 31' attached to thechassis of the automobile to permit the support 28 to swing up and downthus carrying the main pedal 10 bodily with it. From the'foregoing itwill be seen that by the arrangement described, thepe'dal10 has an upand'down swinging movement on the pivot '11,'can be shifted sidewise onthe pivot to the right or to the left, and moved bodily up and down withthe swinging sup port 28.

From the under side of the pedal 10 dc l pends an integral arm 40 havingits lower end 41 rounded ofii' and'adapted to engage either one of thebearings 42, 43', 4Aor 4E5 formed on top of selective members 46,47,

48 and 49,.arranged one alongside the other and inoiuited to slideforward and backward in a recess 50 formed in the top of the support28.Each of the bearings 42, '48, 44 and 45 is rounded off at the front andback (see Fig; 2)'to hold the pedal arm 40 against accidental 'sidewiseshifting liable to be caused'by the action ofthe springs 16 in caseeither is compressed at the time the pedal is shifted from a centralposition to either the right or left. Each of the selective members 46,47, 48, 49 is provided with a rearwardly extending pin 51 having a head52 slidably engaging a recess 53 formed in a bolt 54, and the head 52 ispressed on by a spring 55 arranged in the recess 53 and bearing againstthe rear end wall of the said recess to yieldingly hold the bolt 54 onthe pin 51. The bolts 54 of the several selective members 46, 47, 48 and49 are adapted to engage keepers 60 formed in the heads 61 of actuatingmembers 62, 63, 64 and 65 arranged one alongside the other, and betweenthesidearms 29 and 30 of the support 28. The rear ends of the actuating.members 62, 63, 64 and 65 are mounted to gage friction rollers 70 and71 journaled on speed gear-of the gear set,

the upper end of a lever 72 mounted to rock on a rod 78 attached tothechassis of the automobile. The lever 72 is connected with a link 74connected with the device onwhich the selective controlling mechanism isused.

7 The cams 68 and 69 are disposed in opposite directions and are adaptedto engage friction rollers 75 and 76 journaled on the upper end of alever 77 mounted to rock on the rod 73 and connected by a link 78 withthe device on which the selective controlling mechanism is used and inwhich a change is to be efi'ected, In case the selective controllingmechanism is used on'an automobile, the actuating member 62 controls thehigh member'63 controls'the first speed, the actuating member 64-controls the second speed, and the actuating member 65 controls vthereversing mechanism. Itwill be noticed that the cams 66 and 68arearranged to impart a forward swinging movement to the levers 72 and77 on swlnging the actuating members 62 and 64 downward, and the camsand 67 and 69 are so arranged that a rearward swinging movement is givento the levers 72 on swinging the actuating members and downward. It isunderstood that the actuating members 62, 63, 64 and65 together' withtheir cams-66, '67, 68 and 69 form swinging cam arms adapted toactuatethe levers 72 and 77, as above explained,

the actuating The arm of the pedal 10 is provided with a spring 85bearing-with its free end ona transversely extending rod 86 held on acover 87 fastened to the top of the support 28 and extending acrosstheselective members so as to hold the same against upward movement inthe recess 50 in which the selective members are mounted to slide, aspreviously explained. A set screw 88 mounted on the arm 40 engages thespring 85 'to permit of adjusting the tension of the said spring; Itwill be noticed that when the pedal 10 is shifted sidewise, the arm 40and the spring 85 move with it, and the free end of the spring 85 slidestransversely on the rod 86. The spring 85 holds the pedal 10 normally inuppermost position as shown in Fig. 1. The cover 87 is provided at itsforward edge with forks or guideways 89 into which the lower end (if thearm 40 is adapted to ass on swinging the pedal 10 downward tlius holdingthe arm 40 against accidental sidewise movement as long, as the pedal ispressed down.

One of the side arms 29 or 30 of the support 28 is provided at itsfulcrum end with an angular arm 90 connected by a link 91 with thethrow-out clutch mechanism to throw out the clutch whenever the support28 is swung downward, as previously eX- plained. Thus the throw-outclutch is actuated immediately prior to a change in the device on whichthe selective controlling mechanism is used. It will also be noticedthat the-usual spring 'of this clutch causes the support 28 to return tonormal upper; most position when releasing the downward pressure on thesupport.

In order to prevent accidental sidewise shifting of the arm 40 and itspedal 10 during the time the support 28 swings down and up, or anactuating member-62, 63, 64 or 65 is down in selective position, thefollowing arrangement is made: Each of the heads 61 of the actuatingmembers 62, 63, 64, 65 is provided with a double cam 95 engaged by afriction roller"96 journaled on a bar 97 mounted to slide in a bearing98 attached to the under side of the support 28. The bar 97 is pressedrearwardly by a spring 99 to hold the correspondin friction roller 96 inengagement with the corresponding cam 95. Each of the bars 97 ispivotally connected with a locking arm 100 fulcrumed at its lower end at101 on the support 28, and each locking arm 100 is provided with arearwardly extending locking fork 102 normally out of the path of thearm '40 but adapted to engage the said arm 40 on swinging the support 28downward owing'to the friction ,roller 96 traveling down on the '.lowerportion of the double cam 95. It is understoodthat whenever ,the support28 is swung downward, as "previously explained, and one of the actuatlngmembers 62, 63, 64

y or 65 is carried along then the friction rollers actuating membersremaining in uppermost 96, in engagement with the cams 95 on the arms100 areswung rearwardlyand their .forks 102: move into the .path of thearm 40 thus pretenting s'idewise shifting ofthe arm 40 and consequentlyofthe .pedal- 10. During the: return movement of the support and whilethe selective actuating member re-- mains in lowermost position, thefriction roller 96 of this actuating member travels on the upper portionof its cam 95 and hence the corresponding locking member 100 is causedto swing rearward-so that its fork engages the arm 40 and locks. thesame against sidewise movement. It is understood that during the returnmovement of :the support 28 the friction rollers 96 of the non-selectivemembers reengage their cams ing in lowermost position.

and swing the locking members 100 forward out of the path of the arm 40which latter, however, is held locked by the other fork controlled bythe selective member remain- In order to move the arm 40 into engagementwith the selective member 49 for the 7 reverse actuating member 65, itis hecessary for the operatorto actuate an auxiliary or supplementalpedal 110 arranged alongside the flange 17 of the main pedal 10. Theauxiliary pedal 110 is mounted to swing loosely on the rod 11 as thefulcrum, and is.

pivotally connected by a link 11-1 with "a lever 112 fulcrumed at 113near the lower end of the pedal arm 40. A spring 114 connects the arm 40with the lever 112 to normally hold the free end of this lever 112 inengagement with'one side of a 'lug 115 arranged on thetop of the plate87 intermediate the selective members 48 and 49. As.-

the lever-112 is mounted on the pedal arm 40 it is evident that thelatter cannot be shifted sidewise into engagement with the selectivemember 49 until the lever 112 is swung upward out of engagement with thelug 115 on, pressing the auxiliary pedal 110. From the'foregoing it willbe seen that by the arrangement described the pedal arm 40 cannotbe'moved into engagement'with the selective member 49 for the reversingmecha- Y nismunless the auxiliarypedal 110, is'first pressed prior toshifting the ma n pedal 10 sidc'wisefrom the left'to theright;

The operation is as follows:

When the several parts are in the position shown in Fig. 1 then theautomobile is running at high speed owing to the actuating member 62bemg in lowermost position, and the other members 63, 64 and 65 as wellas the support 28 being in uppermost posiv tion. Now when it is desiredto change to,

say, second. speed then the operator swings the 'pedal down and bearsdown on it ,to impart a downward swinging movementto the support 28whereby the arm -90 and the link 91 release the clutch. On swinging thepedal 10 downward, as above mentioned, the selective member 46 is causedto slide rear Iward by theaction of the pedal arm 40 and ing member 62'touppermost position; It is understood that the tension of *the springfor returning the support 28 is greater than that of the spring 85.During this return movement of the actuating member 62, its cam 66 actson the friction'roller 7 0 and thus allows the lever? 2 to return tonormal neutral position thereby throwing out the high speed gear andleaving the gear set in neutral position. The pedal 10, is now releasedto permit it to return to normal uppermost position by the action of itsspring 85 thus unlocking the actuating-member62 by withdrawing the bolt54 of the selective member 46 from the keeper 60 of the actuating member 62. The pedal 10 is now shifted side- -wise until the arm 40 engagesthe selective of the actuating member 64. Then the op erator bears downon the pedal to swing the supper-152,8 downward, and in doing so theselective actuating member 64 .is carried along, whereby its cam 68 actson the fricf tion roller 7 5 andthe lever 7 7 to throw the second speedgear of the gear set into action.

The operator next. allows the pedal 10 to 'swingupward to disengage thebolt 54 of.

the selective member 48 from the keeper 601 of the actuating member 64,and then the f operator allows the support 28 to return to uppermostposition with the actuating member 64, however, left inlowermostposition.

'VVhen it-isfdesired now to change from second speed to reverse then thepedal 10 is swung downward and pressed to swing the support 28downwardwhereby the shot-out bolt 54 of the selective member 48 snapsinto the keeper of the actuating member 64 to return the latter touppermost \position on re turning the support 28 and the pedal 10 totheir uppermost positions. The pedal 10 is now released thus unlockingthe actuating .member Gaby withdrawingthe bolt 54 of the selectivemember 48 from the keeper 60 of the actuating member 64. On returningthe actuating member 64, its cam 68 acts on the friction roller 77, thusimparting a return swinging movement to the lever 77 whereby the secondspeed is thrown out of action and the gear set is returned to neutralposition. The operator now presses on the auxiliary pedal 110 to swingthe lever 112'out of engagement with the lug 115 and then the operatorshifts the pedal 10 farther to the right until the arm 40 engages theselective member 49. The above described op-.

eration is then repeated, that is, the pedal 10 is swung downward tomove the selective member 49 rearward to engage the bolt 54 thereof withthe keeper 60 of the actuating member 65, andthe support 28 is now swungdownward and with it the actuatingmember 65 which by its cam 69 actingon the friction roller 76 actuates the lever 77 thus throwing thereversing gear-of the gear set into action.

lVhen the selective controlling mechanism is used on the gear set of aFord automobile see Figs. 5 and'6) then the arm 40 of the pedal 10 'sadapted to engage three selective members 200, 201, 203 havingspring-pressed bolts 204 adapted to engage keepers 205 on the free endsofactuating member 206, 207

and 208 mounted to swing on the rod 31 on which the support 28 ismounted to swing up and down. The actuating member 206 controls the highgear of the gear set, the actuating member 208 controls the low speedand the actuating member 207 controls the reversing mechanism. Theactuating members 206 and 208' are provided with cams 210 and 211, whilethe actuating member 207 is provided at its fulcrum end with an angulararm 212 connected by a link 213 with the reversing mechanism 21 toactuate the same. The-cams 210 and 211 engage friction rollers 220 and221 journaled on arms 222 and 223 secured to the high speed clutch shaft224 connected by an arm 225 and link 226 with the low speed clutch 227.The sup port 28 is normally held in uppermost position by a spring 230connected with an angular arm 231 on the fulcrum end of the support 28.

The operation is as follows Normally the high speed gear is in action(see Fig. '5) and when it is desired to change to neutral position, itis only necessary to press the pedal 10 downward to actuate theselective member 200 and to engage the bolt 2041 thereof with the keeper205 of the high gear actuating member-206. On bearing down on the pedal10 a downward'swinging movement is given to the support 28 thuscarryingthe high speed actuatinginemher 206 along to, shift the gear setto neutral position. The operator new releases the 28. is swung downwardinto the actuating member .bearing on the in lowermost position and toallow the support 28 toreturn to uppermost position. When it is desiredto throw in the low gear, the pedal 10 is shifted sidewise to engage thearm 40 with the selective member 203 and then the pedal is swungdownward to cause the selective member 203 to be shifted rearwardly toengage its bolt 204; with the keeper 205 of the actuating lever 208. Theoperator then bears down on the pedal 10 to swing the support 28downward thus carrying the actuating member 208 along and thereby movingthegear-set into low speed position. The operator now releases the pedal10 to withdraw the bolt 20 1 of the selective member 203 from theactuating member 208 to leave the latter in lowermost positionwhileallowing the support 28'to return to uppermost position.- r v 1When the gear set is in high gear position.v and it is desired to go tolow speed position, then it is only necessary for the operator to shiftthe pedal 10 sidewise to engage the arm 40 with the selective member 203and then the operator swings the pedal 10 downward to lock the selectivemember 203 to the actuating member 208, and then the support lowermostposition with the actuating m'ember 208 and the latter is left-there onreleasing the pedal 10 and disengaging the selective member 203 from theactuating member 208. When running in low gear and desiring to change tohigh gear, it is only necessary'to press down the pedal 10 to pick upthe actuating member 208 and to return it touppermost position thusgoing automatically into high gear. When using the selective controllingmechanismfor controlling the service brake and the'emergency brake of'anautomobile, for

When thepressure on the pedal is released, the support 28 remains normally inuppermost position thus releasing the service brake.

The actuating member 303 is provided at its under side with a cam 310 afriction roller 311 journaled on a lever 312 connected by a link 313with the emergency adapted to engage neoapee brake to actuate the latter-onswinging the actuating member 308 downward at the time the arm 40 ofthe pedal is in engagement with the selective member 300 and hasactutime the arm 40 is in the position'shown in.
